GAS DENSITY METER

NORTHDOME® is a unique transmitter that measures in real-time

gas density and temperature. With its small footprint and stainless

steel construction, NORTHDOME® is ideal for OEM applications

such as being embedded into gas analytical instruments or gas

metering systems. Its approved design for use in hazardous areas

and its compactness give the NORTHDOME® the assets to bring

gas density and temperature monitoring into a wide range of

applications.

The fast response time and high repeatability provided by the

patented MesoScale® design offer a unique opportunity to stay

close to composition changes whether in laboratory or process

conditions. Installed in a tank or through tubing, its “plug & play”

capability leads to easy on site deployment which contributes to

simplify and provide safer systems.
